Description

TECHNICAL FIELD

[0001] The present patent application relates to the weaving method of towel fabric, in particular to the weaving process method of towel fabric woven by common jacquard sword loom. BACKGROUND

[0002] Towel fabric is a double warp and above warp organization of jacquard fabric, and the terry loop is formed by the loop of the ground warp, and the jacquard pattern of the fabric is displayed on the ground organization. As a conventional towel fabric, the ground warp and the terry warp both use cotton yarn or polyester cotton yarn.

[0003] If the towel fabric is woven by the common jacquard sword loom, the special feature of the conventional jacquard sword loom is that the eye plate is divided into front and back zones. Taking a conventional jacquard sword loom loaded with 24 columns of eye plates as an example, the number of the guide needles of the equipment is 2160, the number of the pattern is 3, the width of each pattern is 70.34 cm, the design of the warp density on the loom is 78 / inch, and the design of the weft density on the loom is 48 / inch. Since the loom eye plate is loaded with front and back zones, i.e. the 24 columns of eye plates are divided into front and back zones, i.e. the front zone is also the ground warp, and the back zone is also the terry warp; the guide needles are not divided into front and back zones. According to the above loading mode, in the process of deriving the design, the effect of the design obtained by inputting the organization according to the conventional method is that the first 12 vertical lines of the ground warp are the ground warp, and the 13th to 24th vertical lines are the terry warp, and so on. Since only the terry warp is raised, it can be seen that there are 12 ground warps skipping transition at the connection between the terry warps, which causes the edge of the pattern to have skipping connection and present sawtooth transition phenomenon. The final woven product has the quality technical problems of discontinuous pattern, stiffness and serious impact on the appearance of the product.

[0004] After repeated research and analysis, it is finally found that the technical reason is that the loom is a common loom with a straight threading, and the operator inputs the sample card to the CAD program according to the design requirements of the pattern, and the CAD program forms the design drawing from the sample card, which is usually in the form of organization design drawing, and then the sample card is converted into a guide plate file.

[0005] As described above, due to the speciality of the front and rear partition mounting of the conventional jacquard sword weaving machine, that is, the pattern needle mounting is not partitioned, and the eye plate is partitioned, the first 12 roots of the eye plate are the front area and the ground warp, the 13th-24th roots are the rear area and the pile warp, the pattern needle arrangement corresponds to the eye plate, that is, the first 12 roots of the pattern needle are the ground warp, and the 13th-24th roots are the pile warp, and the pattern needle presents a cross jumping arrangement. Since the design drawing of the CAD program is in the form of an expanded drawing, the first 12 longitudinal lines are displayed as ground warp, and the 13th-24th longitudinal lines are displayed as pile warp, and the two are alternately staggered. Since the towel fabric product only has pile warp, the ground warp does not have pattern, and there are 12 ground warp intervals between the pile warp parts on the design drawing, which causes the pile warp pattern to jump at the connection, and the sawtooth shape is obvious, which makes the jacquard pattern not beautiful. Due to the special mounting form of the conventional jacquard sword weaving machine, the design is in the normal CAD program, which causes the pattern conversion to have problems, and if tussah silk is used as the pile weaving raw material, the problem is particularly prominent, which causes the product design to fail and enters the bottleneck period of new product research and development. SUMMARY

[0006] The application of the present patent application aims to solve the technical problems of the ordinary jacquard sword weaving machine in weaving double-warp jacquard fabric, especially towel fabric, which has a sawtooth transition phenomenon at the edge of the product pattern after inputting the computer CAD program due to the partition mounting of the eye plate, which causes the weaving pattern to be discontinuous, jumping and hard, and difficult to be beautiful, and provides a weaving application of a jacquard sword weaving machine with a patterned towel fabric.

[0007] The weaving application of a jacquard sword weaving machine with a patterned towel fabric provided by the present patent application has the following main technical contents: a weaving application of a jacquard sword weaving machine with a patterned towel fabric, and the method is as follows:

[0008] ①. According to the weaving design drawing of the towel fabric, the warp design part is divided into a ground warp group and a pile warp group;

[0009] ②. Obtain a CAD program sample card

[0010] The inner warp of the CAD program sample card corresponding to the warp part is divided into a front half area and a rear half area corresponding to the ground warp group and the pile warp group;

[0011] The first 12 columns of the warp grid of the front half area corresponding to the machine eye plate are all changed to an integer not less than "2" from the original number "1" in the sample card, which is used as the organization area of the ground warp group, and is fixed organization for CAD program design;

[0012] The 13th-24th columns of the warp grid of the rear half area are kept as the original number "1", which is used as the organization area of the pile warp group;

[0013] III. The latter half area, i.e. the organization area of the pile warp group, corresponds to the input of the pattern structure to determine the design;

[0014] The former half area, i.e. the organization area of the ground warp group, is output to the sample card.

[0015] The towel fabric is double warp and more than two kinds of jacquard fabric. The technical solution of the jacquard rapier loom disclosed in the patent application is applied to the weaving of the towel fabric with pattern, which is matched with the self-assembly characteristics of the jacquard rapier loom, and uses the program setting characteristics that the digital "1" area of the CAD program sample card can be set with multiple organizations, and the area with other numbers can only be set with one organization. In the input of the CAD program sample card, the ground warp and the pile warp of the jacquard product are separated, and the ground warp organization is set with data greater than "1" in the sample card and is output to the design organization alone, while the part with data "1" in the sample card is only used for CAD program design of the pile warp organization, so as to achieve reasonable conversion of the organization and form the design with the organization. Only the pile warp part exists on the design, and the pile warp organization on the design is continuous and is not separated by the ground warp, so the edge of the pattern is not disconnected and the edge sawtooth phenomenon is overcome. Finally, the technical bottleneck is broken and the sawtooth and fracture phenomenon at the connection of the pattern is eliminated. The technical solution adopts the technical concept and means of dividing the warp into ground warp and pile warp in the CAD program sample card design and processing them differently, completely solves the technical problem of hard transition and obvious sawtooth at the edge of the pattern, realizes the technical problem of weaving the towel product by the conventional jacquard rapier loom, and presents a very perfect appearance effect for the flower or geometric pattern of the towel product made of cotton yarn, polyester cotton yarn, especially tussah silk, which opens up a new product type of tussah silk in the towel product. BRIEF DESCRIPTION OF DRAWINGS

[0017] Figure 2 It is the inner warp segment diagram after digital division of the CAD program sample card. The towel fabric weaving of the loom should DETAILED DESCRIPTION

[0018] The following specific embodiment will explain the application of the jacquard rapier loom to the weaving of the towel fabric with pattern in detail, but the protection scope of the patent application is not limited by the following technical description.

[0019] The woven product is a large jacquard tussah silk towel quilt, and the selection of the raw materials is as follows:

[0020] Warp silk:

[0021] Ground: 1 / 40 s / 2 combed cotton yarn

[0022] Wool warp: 1 / 68 N / 2 tussah silk yarn

[0023] Weft: 1 / 40 S / 2 combed cotton yarn

[0024] The selection of raw materials for this product is a big feature. The wool warp of the terry loop is tussah silk yarn, which directly contacts the skin and has a natural comfortable cool feeling.

[0025] The conventional installation of the jacquard sword weaving machine is as follows:

[0026] Number of pattern needles: 2160 needles Number of patterns: 3 patterns

[0027] Warp density on the machine: 78 ends / inch Weft density on the machine: 48 ends / inch

[0028] Pattern width per pattern: 70.34 cm Number of hooks: 39 hooks / inch 2 passes

[0029] The eyelet board has 24 columns, divided into front and back sections. The front section is ground warp, and the back section is wool warp. The pattern needles are not divided into front and back sections and are arranged in a straight pass.

[0030] The eyelet board has 24 columns, divided into front and back sections. The front section is ground warp, and the back section is wool warp. The pattern needles are not divided into front and back sections and are arranged in a straight pass.

[0031] On the CAD computer program design:

[0032] ① According to the towel quilt pattern design, the warp design part is divided into ground warp group and wool warp group;

[0033] ②. Obtain CAD program sample card

[0034] The inner warp of the CAD program sample card corresponding to the warp part is divided into the front half and the back half corresponding to the ground warp group and the wool warp group, as shown in Figure 1 and Figure 2 ;

[0035] The front half corresponds to the machine eyelet board, and the first 12 columns of the original number of warp grids are all changed to an integer not less than "2" as ground warp organization area. For CAD program design, it is a fixed organization.

[0036] The rear half area, corresponding to the machine card, retains the original assigned digital "1" of the warp check of columns 13-24 as the base warp organization area;

[0037] ③. The rear half area, i.e. the base warp organization area, is input according to the pattern structure to complete the design of the draft, and the draft only reflects the base warp organization;

[0038] The front half area, i.e. the ground warp organization area, is output to the sample card and is not reflected in the draft.

[0039] The number "2" displayed in the sample card is the fixed ground warp, which is directly input. In this way, the number of needles in the draft is reduced by half, from 2160 to 1080. Since the ground warp is not included, only the base warp pattern organization is displayed, and the 12 ground warp intervals between the base warp groups are eliminated on the draft. This scheme opens up a new technical design approach. In the sample card design, the original method of outputting the ground warp and the base warp together is changed to separate the ground warp and the base warp by numbers. The ground warp organization is output separately in the sample card, while only the base warp organization is reflected in the draft. This achieves reasonable organization conversion and completely solves the technical problem of the hard transition and obvious jagged edges of the pattern. It also realizes the technical difficulty of weaving towel products on a conventional jacquard sword weaving machine. Whether the designed pattern is a flower or a geometric pattern, it presents a very perfect appearance. This scheme opens up a new product type for tussah silk in towel products.
